Unofficial Installation Guide

This is an unofficial installation guide. It may be outdated or apply only to very specific configurations and versions. The official and maintained installation steps for RT are in the README and UPGRADING documents included in the official .tar.gz packages.


This page contains out of date and possibly misleading information or instructions such as installation methods or configuration examples that no longer apply. Please consider this warning when reading the page below.

Installing RT 3.6.6 on Redhat Enterprise 5.x

For updates to this guide and its packages visit: http://blog.jwhite3.com

New yum repository info for RHEL5 is availble here: http://wiki.bestpractical.com/view/RHEL5RepoArchive

As of Fedora 6 rt-3.6.3 has been available as an RPM. The Fedora RPM has since been rebuilt for Rhel5 using the rt-3.6.6 source code. This document serves as a guide to the basic install and setup of a new (virgin) instance of RT.

This guide only works for i386 versions of RHEL 5/5.1. x86_64 requires different packages which are not included in this bundle. The packages can (generally speaking) be installed with CPAN with minimal fuss, although you may be able to locate RPMs elsewhere.


This document assumes you have basic system admin experience and root access to the server you are installing on. In addition you require...

• Redhat Enterprise 5 or 5.1 base install

• yum configured to provide all ‘base’ packages available on the installation media.

OS Setup

Install Redhat Enterprise 5 with mysql and apache. Also, you will likely need to disable SELinux, or follow the directions on that page. As stated above this guide will assume that all ‘base’ packages must be available via yum. It is also assumed that this server will not only host the rt web front end, but will also house the rt database using mysql.

• Disable SELinux or put it in to permissive mode

setenforce 0

• Update your installation with the latest patches

yum update

• Install Apache, MySql, & sendmail-cf via yum

yum install httpd

yum install mysql
yum install mysql-server
yum install sendmail-cf
• Start the httpd and mysql services

service mysqld start

service httpd start
• Make sure the httpd & mysqld service start at boot

chkconfig httpd on

chkconfig mysqld on

RT Installation

With the OS correctly installed and apache & mysql running, we can now install Rt and all of it dependencies. This can be done via two methods supported by this document, yum or rpm.

• Download this archive and extract it.

wget http://www.makestorm.com/files/rt/rt-3.6.6-bundle.tar.gz

tar –zxvf rt-3.6.6-bundle.tar.gz
• Setup a local or remote yum repository to serve these packages

vi /etc/yum/repos.d/localrt.repo


name=RT 3.6.6 for Red Hat Enterprise Linux 5.1
• Clean your yum cache, download new repo data, and make sure rt3 exists

yum clean all

yum list rt3
• Install rt3 and all dependencies with yum

yum install rt3

On a fresh machine yum will install about 84 total packages...

RT Post Setup

Now that rt is installed you may want to customize your setup. Inorder to do that you will need to know where your files are located. This package changes the file locations from the fedora6 version of rt,and differs greatly from the BP default.

bindir:               /usr/sbin
sysconfdir:           /etc/rt3
htmldir:              /usr/share/rt3/html
logfiledir:           /var/log/rt3
masonstatedir:        /var/cache/rt3/mason_data
sessionstatedir:      /var/cache/rt3/session_data
customdir:            /usr/local/rt3/
custometcdir:         /usr/local/rt3/etc
customhtmldir:        /usr/local/rt3/html
customlexdir:         /usr/local/rt3/po
customlibdir:         /usr/local/rt3/lib
• Customize /etc/rt3/RT_SiteConfig.pm

You may find a need to change the site configuration of rt from time to time. For example to point rt to a remote database, configure external authentication, or set other configurable options. Below are several options that I like to set, but keep in mind these may differ greatly from a standard configuration.

Set($WebExternalAuth , '1');
Set($WebFallbackToInternalAuth , '1');
Set($OldestTransactionsFirst, 0);
Set($MyTicketsLength, 25);
Set($MyRequestsLength, 25);
Set($WebBaseURL , "<a href="http://rt.example.com" class="external free" rel="nofollow">http://rt.example.com</a>");
Set($WebPath , "");
Set($WebImagesURL , $WebPath . "/NoAuth/images");
Set($rtname, 'example.com');
Set($DatabaseHost   , 'db.example.com');
Set($DatabaseRTHost , 'localhost');
Set($DatabaseUser, 'dbuser');
Set($DatabasePassword , 'dbpassword');
Set($DevelMode, '0');
Set($ShowTransactionImages, 0);
Set($SuppressInlineTextFiles, true);
• Initialize the RT database

Assuming that you will host both the rt web service and the database on the same server (unlike the custom config above) you will need to create a new rt3 databse instance. This is done in one simple step from the command line.

rt-setup-database --action init

Configure sendmail

• Symlink rt-mailgate to /etc/smrsh, and create aliases to use RT:

ln -s /usr/sbin/rt-mailgate /etc/smrsh/rt-mailgate

Edit /etc/aliases and add lines:

rt: "|/etc/smrsh/rt-mailgate --queue general --action correspond --url http://your.host.name/"

rt-comment: "|/etc/smrsh/rt-mailgate --queue general --action comment --url http://your.host.name/"
• Edit /etc/mail/sendmail.mc and change the line:

DAEMON_OPTIONS(Port=smtp,Addr=, Name=MTA')dnl

to read:
dnl DAEMON_OPTIONS(Port=smtp,Addr=, Name=MTA')
• Add the following lines to your sendmail.mc file, filling in your ISP's mail server (optional):


FEATURE(authinfo',hash /etc/mail/auth/client-info')dnl
• Rebuild your sendmail.cf:

m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf

• Add rt server alias to /etc/mail/local-host-names:


• Restart sendmail:

service sendmail restart

Test your new RT instance

Login to your new RT instance and test things out.

Default URL : http://yourdomain.com/rt3/

Default User:  root
Default Pass:  password

RedHat Updates Warning

RedHat seem to be shipping updates to perl via yum that have been built in a way that is not compatible with RT.

Specifically Scalar::Util and possibly File::Temp too*.

If RT stops running after an update please install these via CPAN and restart apache.

You can install them using from the command line:

cpan File::Temp cpan Scalar::Util
